I successfully installed Ubuntu Desktop 22.04 LTS on a HP ENVYx360 laptop, using a bootable USB I created with Rufus.
After updating the system, I then installed the KDE-standard metapackage, to evaluate it. It installed ok, but when I restarted, it never worked again. It fails to boot in normal mode. In safe mode I tried a few things (dpkg fails, fsck fails, updated grub) but it didnt solve it. The crazier thing is that when I tried the same bootable USB medium in order to reinstall, that fails too!
During the boot/checks several services (snapd.service, modem manager, hostname service, etc) fail to start and the system just perpetually reattempts to restart them..
Any ideas?
